Title: Semiconductor ic
Inventor: KOMATSU TAKEO
IPC: H01L27/02
Filed: 1979-07-26
Abstract: PURPOSE:To protect an FET gate from an instantaneous high voltage caused by a static electricity charged on a human body by a method wherein an NPN-type transistor and an MOS transistor are provided between an input terminal of  MISFET, with which an IC is constituted, and an earth terminal. CONSTITUTION:The input terminal T is connected to a gate of the MISFET element 2 to be protected and the earth terminal E is connected to a source or a drain of the element 2 and the element 2 substrate. Then, in order to protect the element 2 from an instantaneous high voltage, a transistor emitter is connected to an input terminal and a collector is connected to the earth terminal E using an NPN-type transistor 8 and an MOS transistor 9. In addition, the source and drain of the MOS transistor 9 are connected between the base of the transistor 8 and the earth terminal E and the transistor 9 substrate is grounded. As a result, when an overvoltage is applied to the input terminal, the transistor 8 bypasses it instantly and no damage is given to the element 2 gate.

Title: Ink feeding pump
Inventor: TAKAHASHI TAKAO
IPC: F04B17/04
Filed: 1981-06-23
Abstract: PURPOSE:To shorten the rise time required for raising the pressure of ink to a required pressure and to remove pulsation of ink flow, by employing such an arrangement that ink pressurized to a proper level is discharged continuously during recording time and drawn during non-recording time. CONSTITUTION:When a coil assembly 8 of a voice coil type linear motor is retracted by passing current through a voice coil 7 during non-recording time, for instance, in the period required for retracting of the nozzle head of a printer, pressure in an ink pressurizing chamber 3 becomes negative and ink is drawn into the chamber 3 via a check valve 1. When the coil assembly 8 comes into abutment with a stopper 12, current supply to the voice coil 7 is stopped. On the other hand, by passing current through the voice coil 7 in a reverse direction in starting recording operation, the coil assembly 8 is forced out into the ink pressurizing chamber 3. Resultantly, ink in the chamber 3 is pressurized by a bellows-diaphragm 6 and discharged to the outside from a check valve 2.

Title: Reflection mirror antenna
Inventor: MIYAHARA NORIO
IPC: H01Q19/19
Filed: 1988-04-19
Abstract: PURPOSE:To easily adjust the title antenna in the direction of its radiating beam by inclining the direction of a primary radiator along the normal to its effective area from the mirror axis direction of a main reflecting mirror in the plane of symmetry in the structure of the antenna. CONSTITUTION:When the direction of the primary radiator 3 along the normal to its effective area is made coincident with its center axis direction, the intensity of the electric field projected on an auxiliary reflecting mirror 2 becomes different from each other at points S1 and S2. When, for example, theta1>theta2, radio waves cannot be projected effectively against a main reflecting mirror 1 and the gain declines because the intensity of the electric field at the point S1 becomes lower than that at the point S2. Therefore, the opening of the radiator 3 is cut so that the direction of the radiator 3 along the normal to its effective area can be inclined toward the higher side where the intensity of electric field is higher than the other side in the plane of symmetry in the structure of this antenna. As a result, the direction of the radiating beam of the primary radiator 3 is changed and the intensities of electric fields at the points S1 and S2 can be made equal to each other. Therefore, radio waves reflected by the auxiliary reflecting mirror 2 are effectively projected on the main reflecting mirror 1 and the decline in gain can be prevented. In addition, the direction adjustment of this antenna becomes easier.

Title: Stencil paper for thermal stencil printing
Inventor: YAMADA HIROMICHI
IPC: B41N1/24
Filed: 1988-04-19
Abstract: PURPOSE:To obtain a stencil paper having favorable image properties, generating little offset of an ink, having good plate wear characteristics and favorable handleability, by composing a porous support of a thin paper made in a laminate form from at least two paper layers differing in density. CONSTITUTION:A porous support comprises a thin paper made in a laminate formed from at least two paper layers differing in density, in a stencil paper for thermal stencil printing which comprises a thermoplastic resin film and the porous support laminated with each other. Due to the use of the above- mentioned thin paper, adhesion of the resin film to the lower-density paper layer side results in that the number of adhesion points between the film and the paper is reduced, favorable image properties are secured, permeation of an ink is controlled by the higher-density paper layer not making contact with the film, offset is prevented from occurring, and plate wear characteristic is enhanced. When the resin film is adhered to the higher-density paper layer side, the permeation of the ink is controlled by the paper layer making direct contact with the resin film, offset of a printed image is prevented from occurring, and favorable handleability required of a stencil paper for thermal stencil printing can be secured by the lower-density paper layer.

Title: Substrate having built-in capacitor
Inventor: NAMIOKA MAKOTO
IPC: H01G4/00
Filed: 1989-04-18
Abstract: PURPOSE:To obtain an objective capacitor of small capacitance even if the same part of high dielectric constant with a capacitor of large capacitance is used as a dielectric layer by a method wherein a pair of terminal electrodes which constitutes a capacitor is provided in parallel only along the surface of a part of high dielectric constant. CONSTITUTION:A substrate 10 may be a ceramic substrate adapted for a hybrid ICs, and a high dielectric constant part 11 may be formed in a region in which a capacitor is built. When a capacitor is formed taking advantage of the high dielectric constant part 11 as a dielectric layer, only one side of the part 11 is employed and a pair of terminal electrodes is built thereon separate from each other by a certain distance. Therefore, even if the high dielectric constant part 11 is formed large enough in dielectric constant to be adapted for making a capacitor of large capacity be built in the substrate 10, capacitance obtained between a pair of electrodes 11 of a built-in capacitor can be made small enough. The distance between a pair of electrodes 22 can be optionally set to some extent, so that an objective capacitor of small capacitance can be comparatively easily and accurately obtained by enlarging the distance concerned.

Title: Gas concentration measuring probe
Inventor: IIDA NORIMASA
IPC: G01N27/18
Filed: 1993-03-31
Abstract: PURPOSE:To obtain a gas concentration measuring probe which has a heat resistance and can be easily manufactured with high reproducibility and the pores of which have high reproducibility by stretching a resistance thin wire across the front end of a ceramic tube and airtightly putting a cap having a bottom hole on the front end. CONSTITUTION:As a gas in a ceramic tube 1 is sucked out through a suction port 36 by means of a vacuum pump, the tube 1 inhales an atmospheric gas to be measured through the hole 21 of a cap 20 and the inhaled gas collides with a tungsten wire 8 stretched extremely near the hole 21 and removes heat from the wire 8. The heat radiating amount from the wire 8 varies depending upon the flow velocity, thermal conductivity, and density of the gas flow around the resistance thin wire 8, the temperature difference between the thin wire 8 and its surrounding gas, and the diameter and length of the wire 8. Therefore, the resistance of the wire 8 changes and a measuring circuit connected to the front end of an output terminal detects the change, and then, the gas concentration in the atmosphere to be measured is calculated from the changing state of the resistance.
